Priorslee Balancing Lake and The Flash

4.0°C > 6.0°C: Early cloud clearing for while. Light south-westerly breeze. Very good visibility.

Sunrise: 07:38 GMT

* = a species photographed today
$ = my first sighting of the species for this year
$$ = my first ever recorded sighting of the species in the area

Priorslee Balancing Lake: 06:15 – 09:25

(280th visit of the year)

Bird notes:
- the two Canada Geese that flew in yesterday remain.
- the returning Greylag Geese flock was seen after a few days absence. Just one of the mainly-white feral geese with them.
- for the first time as long as I can remember there were no Mute Swans present.
- a pair of Pochard seen again: did I overlook them yesterday?
- the Water Rail was heard calling from the north-east area again.
- a strong passage of Wood Pigeons, initially heading north-west; later mostly more westerly.
- where the Black-headed Gulls today? I noted my first at 07:35. My highest count was a mere thirteen.
- by contrast Lesser Black-backed Gulls started to arrive by 06:50. Early arrivals came from the South with later arrivals streaming in from the north-east. At least 300 were involved. I noted 64 arriving after 08:00.
- only three Song Thrushes were heard singing. The Blackbird was silent today.
- two Cetti's Warblers noted: the usual singing male and another calling bird.
- a Reed Bunting was heard calling in the south-west area. This species remains scarce.

- *138 Greylag Geese: 131 inbound together preceded by seven

Noted on the West end street lamp poles pre-dawn:

Springtails:
- *1 small unidentified springtail

Bugs:
- *1 $$ ground-bug Scolopostethus thomsoni or similar

Spiders, harvestmen etc.:
- 2 harvestmen Paroligolophus agrestis

Later on the Teece Drive fence or elsewhere:
Nothing noted

Not much to see of the Beaver Moon.

Pre-sunrise a bank of cloud clearing to the East with some medium-high cloud beginning to pick up colour.

Colouring well.

At its best according to my smart phone.

And again this what my "big camera" made of the sunrise.

The next bank of clouds gathering to the West. Not many leaves left on the trees after the storm.

I counted them so you don't have to! There are 132 geese here: 131 Greylags and one mostly white feral bird. Seven Greylags had preceded them by a minute or so. The wide-angle available on the camera is a boon here.

For some reason the gulls are currently eschewing the two platforms and deciding to use the concrete platform. Two first-winter Herring Gulls among Lesser Black-backed Gulls. This photo illustrates a problem I have with the camera. The legs of the Lesser Black-backs are strikingly yellow in real life. You would not know that here and the colour difficult to distinguish from the pink legs on the first-winter Herring Gull in the foreground.

The gull union: "one out all out".

A very (very) small part of one of the migrant Wood Pigeon parties.

Not what fishermen like to see. Six Cormorants here.

Celebrating its success in chasing the other Grey Heron away this one gives me a fly-past.

A flying barn door!

Look no wings! Full marks and a gold star if you can identify this.

Give up? It is a Cetti's Warbler!

A two-fer: the larger insect is a ground-bug Scolopostethus thomsoni or similar. Obsidentify was sure though NatureSpot would want me to have examined the underside to exclude other similar species. Noted as active all year. Whatever: it is a new species for me. The other insect is a springtail, much smaller than others of this overall shape that I have seen.

In the Priorslee Avenue tunnel pre-dawn:

Cold again

Flies:
- 8 midges

Spiders, harvestmen etc.:
- 1 spider only: usual suspect

The Flash: 09:30 – 10:40

(274th visit of the year)

Bird notes:
- still four Mute Swans. The pair from the Balancing Lake staying together. The resident duo spending most of the time well apart.
- two drake (Common) Teal were alongside the island today.
- two drake Pochard were new arrivals.
- a few Goosanders hanging on.

Bird(s) noted flying over here:
- 1 Lesser Black-backed Gull
- 11 Wood Pigeons in a migrant group flying high north-west
- 1 Jackdaw

Noted on / around the water:
- 17 Canada Geese: more inside the island?
- 40 Greylag Geese: more inside the island?
- 4 Mute Swans
- 22 (14♂) Mallard
- *2 (2♂) (Common) Teal again
- 2 (2♂) Pochard
- 13 (7♂) Tufted Duck
- 5 (0♂) Goosander
- *9 Moorhens
- 75 Coots
- *6 Great Crested Grebes still
- *17 Black-headed Gulls
- 2 Herring Gull: immatures
- 9 Cormorants
- 1 Grey Heron
- 1 Little Egret

Noted around the area:

Moths:
- *2 male Mottled Umbers Erranis defoliaria: one of these in the same place for its third day

Bees, wasps etc.:
- *>5 Common Wasps Vespula vulgaris

The two drake (Common) Teal were by the island (with two Black-headed Gulls looking on). It occurs to me that in winters of yore (25 years ago perhaps) the island use to host a day-roost of Common Snipe. That would be good to see again.

"Water off a duck's back" - or in this instance a Moorhen's back. Those feathers sure are waterproof.

A Great Crested Grebe still showing head-streaking indicating this is a first-winter bird.

A portrait of a first-winter Black-headed Gull.

The second of two male Mottled Umber moths Erranis defoliaria. This one is, unusually, both "mottled" and "umber".

It was both cloudy and cold – well below the 10.0°C that is usually needed for insect to be active. Nevertheless there were at least five Common Wasps Vespula vulgaris on the Ivy. This angle shows both the face-pattern and parallel-side yellow flash on the side of the thorax to confirm the species identity.

This illustrates how flexible the "wasp-waist" is.
